[Android Components](../../../README.md) > Concept > Storage

The concept-storage component contains interfaces and abstract classes that describe a "core data" storage layer.

This abstraction makes it possible to build components that work independently of the storage layer being used.

Currently a single store implementation is available:

• syncable, Rust Places storage - compatible with the Firefox Sync ecosystem

Usage

Setting up the dependency

Use Gradle to download the library from maven.mozilla.org (Setup repository):

implementation "org.mozilla.components:concept-storage:{latest-version}"

Integration

One way to interact with a concept-storage component is via feature-storage, which provides "glue" implementations that make use of storage. For example, a features.storage.HistoryTrackingFeature allows a concept.engine.Engine to keep track of visits and page meta information.
